In both The Netherlands and Australia, you have an option to become a donor. I picked up a flyer reminding me of this in The Netherlands, and realised that though I was registered while living in Australia, I have not yet done so in NL. If you have moved between the countries, you might like to also update your preferences with the relevant organisations.
2016 update – there is now an English section on the website, interestingly with an ex-Australian as a spokesperson (this section of the website below is in English but video still in Dutch!) http://www.transplantatiestichting.nl/english
In The Netherlands, register at www.donorregister.nl
In Australia, the website is www.donatelife.gov.au
Both websites have a huge amount of information, so take a look through.
I’ve just registered on the NL site with my Digi-D number. Here are the choices you have here:
Ultimately, it’s your choice in both countries and something you should consider discussing with your family.
